Ivan Iosifovich Proskurov (Russian: ???? ????????? ?????????; 18 February [O.S.
5 February] 1907 – 28 October 1941) was a Soviet pilot and recipient of the title Hero of the Soviet Union, best known as the chief of military intelligence who tried in vain to warn Josif Stalin that the Red Army was ill-prepared to defend the USSR against a German invasion - unwelcome advice which apparently cost him his life.
